<p class='vspace'></p><h2>goto</h2>
<p>Transfers program flow to a labeled point in the program
</p>
<p class='vspace'></p><h4>Syntax</h4>
<p>label: 
</p>
<p class='vspace'></p><p>goto label;  // sends program flow to the label
</p>
<p class='vspace'></p><h4>Tip</h4>
<p>The use of <em>goto</em> is discouraged in C programming, and some authors of C programming books claim that the <em>goto</em> statement is never necessary, but used judiciously, it can simplify certain programs. The reason that many programmers frown upon the use of <em>goto</em> is  that with the unrestrained use of <em>goto</em> statements, it is easy to create a program with undefined program flow, which can never be debugged.
</p>
<p class='vspace'></p><p>With that said, there are instances where a goto statement can come in handy, and simplify coding. One of these situations is to break out of deeply nested <em>for</em> loops, or <em>if</em> logic blocks, on a certain condition.
</p>
<p class='vspace'></p><h4>Example</h4>
<pre>
for(byte r = 0; r &lt; 255; r++){
    for(byte g = 255; g &gt; -1; g--){
        for(byte b = 0; b &lt; 255; b++){
            if (analogRead(0) &gt; 250){ goto bailout;}
            // more statements ... 
        }
    }
}
bailout:
